Recieve USB keyboard data - USB Host Demo?

[stevenlutz]

I'm new to developing with USB and I'm hoping someone can recommend a demo that will take a USB Keyboard as input for either the FRDM-K22F or FRDM-KL25Z

Thank you

Hi @stevenlutz ,

The USB interface in KL27 is device only. It's impossible to connect a USB keyboard.

K22 USB interface is OTG. It can connect a USB device, such as keyboard. Please download FRDM-K22F SDK from https://mcuxpresso.nxp.com/en/welcome. There is a USB host_mouse_keyboard demo in SDK_2.10.0_FRDM-K22F\boards\frdmk22f\usb_examples\usb_host_hid_mouse_keyboard.

Regards,

Jing
